It's probably just a coincidence... but an interesting one!
According to TR's time line, in 1969: " Arizona, Maricopa, Phoenix- TR moves his family; works as an electrician for a man named Otto". This is the same year the Otto i found moved from Prescott to Phoenix.
And then, in 1973: "Arizona, Maricopa, Phoenix – TR moves family; works as an electrician for a man named “Otto” also works in a shoe shop.
April 30th – Arizona, Maricopa, Phoenix – TR is arrested as a Fugitive from Justice, is to hold and individual whom has an outstanding warrant in another state.
The Otto i found, died the 28th of April. The article just mentions his 4 brothers and a sister, all from Ohio, where he was born. It also mentions that he owned a tavern in Prescott "until selling it and move to Phoenix". It doesn't say if he owned a business in Phoenix, nor the cause of death... Nor if he once had a wife and children. But it says he was a member of Moose Lodge in Prescott... :/
